c/c++は文字列処理で他の言語java pythonに及ばず、上の拡張が役立ちます.
行による文字列の読み込み:

stringstream strstream;//#include <sstream>
		strstream<<string(tmp);
		vector<string> lines;
		char buffer[1024];	
		deviceNames.clear();
		while (strstream.getline(buffer,sizeof(buffer)))//c++       
		{
			//DebugA(buffer);
			string delimiter="	";
			pystring::split(string(buffer), lines, delimiter,delimiter.size());
			if(lines.size()>=2)
			{
				if(lines.at(1).compare("device")==0)
				{

					deviceNames.push_back(lines.at(0));
					DebugA(lines.at(0).c_str());
				}
			}
